World boundary

From Minecraft Wiki
Jump to: navigation, search
This article is about the area at the edge of the world. For the phenomenon that existed before Beta 1.8, see Far Lands. For the customizable border wall, see World border. For effects which occur at high distances due to numerical precision loss, see Java Edition distance effects.
The world border, by default, marks the area exactly 1 chunk before the 30,000,000 mark.

The world boundary is the area defining the intended spatial edges of a Minecraft dimension. It is distinct from hard limits, which are defined by limitations of the programming language itself.

Definition[edit]

Java Edition[edit]

Horizontal limits[edit]

The world border is located at X/Z ±29,999,984. Chunks still generate past this point, but the player cannot go past ±30 million blocks out.

There are several different intended horizontal boundaries in the game.

Firstly is the maximum distance nether portals can generate at in the Overworld, at X/Z ±29,999,872 blocks (128 blocks, from the 16 blocks per chunk multiplied by the 8 block multiplier). This limit prevents any surpassing of the next borders using the Nether to multiply distance by 8.

The next layer is the world border, which lies at X/Z ±29,999,984 by default, and establishes an arbitrary (but capped at this default value) blockade to prevent the player from advancing. There are several methods of bypassing this border.

The third layer lies exactly one chunk further, at X/Z: ±30,000,000. At this point, there is an invisible "wall" preventing the player from advancing by setting any players' positions beyond it to it, even in spectator mode. Using commands like /teleport does not work, since the game does not accept any value beyond X/Z: ±30,000,000. This value is hard-coded into the game's source code. Other block interactions, such as TNT exploding or water flowing, affects blocks outside this limit. By using a minecart (in a superflat preset with the top layer as rails), the player can go even further, up to X/Z: ±30,000,496. At that point, the player is frozen in place until the minecart is destroyed, then they are teleported back to X/Z: ±30,000,000.

The fourth and final layer lies at X/Z: ±30,000,496, which can be considered the absolute edge of the Minecraft world, as chunks no longer generate beyond this point, so it's impossible to advance past this point without the use of modifications.

By editing the source code for the game, it is possible to extend the terrain generation and world border past X/Z: ±30,000,240 (up to X/Z: ±2,147,483,647) and experience the game quite normally (no ghost chunks; mobs can spawn alright; commands accept higher values). The game performs normally even at distances of X/Z: ±2,000,000,000, as in modern versions most distance effects have been patched out of the game. It is advisable to take note of what distance effects do exist, as well as the hard limits present - notably the ±33,554,432 lighting stop and hard limit of ±2,147,483,647.

Vertical limits[edit]

The player is able to build up to Y = 256 (320)‌[upcoming: JE 1.18], and down to Y = 0 (-64)‌[upcoming: JE 1.18]. But it is not possible to build any further than that. However, one can still fly with creative mode or an elytra, or use explosives/slime blocks and pistons to get past Y = 256 (320)‌[upcoming: JE 1.17].

In Java Edition from snapshot 20w49a, the height limit could be altered in custom worlds, allowing the ability to build past the height limit (256 (320‌[upcoming: JE 1.18])) and also below the bedrock (y=0 (y=-64‌[upcoming: JE 1.18])). This was reverted and delayed after the decision to delay the parts of the update that dealt with World Generation, this came into effect in 21w15a.

Bedrock Edition[edit]

Horizontal limits[edit]

Bedrock Edition technically has no hard boundary, and the world at far distances is far too ravaged by several distance effects to provide any semblance of reasonable gameplay. Nonetheless, there do exist intentional defined limits for some game functionality:

  • It is impossible to teleport beyond X/Z ±30,000,000 using commands in the vanilla game. Any attempts to teleport further puts the player back to this coordinate. Attempting to use any block placement command results in an error message. Despite this, it is still possible to use structure blocks and the /locate command.
  • X/Z ±31,999,872 are the maximum coordinates reachable in the Overworld via Nether portal. The only way to teleport beyond these coordinates is to use external tools (such as a world editor).

Vertical limits[edit]

The player is able to go to Y ±30,000,000 but it is impossible to teleport beyond these coordinates without the use of external tools.

Effects[edit]

Java Edition[edit]

Generally, long server response times caused by massive distances produce unintended results, but most blocks and entities behave normally, with a few exceptions:

  • Water and lava fall normally, albeit at a much slower pace due to long response times.[verify]
  • Extended pistons may sometimes not render until they receive another block update.[verify]
  • Beyond the X/Z ±30,000,000 mark:
    • Mobs do not spawn at all.
    • Lighting does not update (with exception to sunlight and moonlight).
    • Items may jitter slightly.

Beyond this, most of the unintended behavior of blocks and entities is caused by either the world border (as detailed here), or being sufficiently far from the world origin (see this page). Some odd effects which are attributed to the boundary itself are as follows:

  • Attempting to walk into the boundary will still display a walking animation, walking sounds and cause view bobbing, effects which are not present for walking into the world border or solid walls. Mojang has decided not to fix this issue.[1]
  • Using elytra to fly into the border will cause the flying sound to continue to play at full volume rather than quietly or not at all.[2]
  • Rain particles will always hit the ground at exactly sea level regardless of the actual shape of terrain beyond 30 million blocks. Mojang have decided to also not fix this.[3]

History[edit]

Horizontal boundaries[edit]

This section is missing information about Console Edition boundary and effects, 3DS edition boundary. 
Please expand the section to include this information. Further details may exist on the talk page.
Java Edition pre-Classic
rd-131655The world has an edge which can be fallen off of indefinitely. Where this edge exactly is is unknown nor is if it is constant between worlds, however it is 256 blocks long in both directions.
Java Edition Classic
0.0.12aThere is now a solid border at the edge of the world. Where exactly this edge is is unknown, and it may vary from world to world.
An "infinite" ocean (consisting of a layer of water atop a thick bedrock column) will extend past the world boundary rather than being just void. Where this ocean truly ends is unknown, and if said ending is intentionally programmed is also not known. Interestingly, this used the old water texture even when water itself was updated to have a newer texture.
These fake blocks beyond the boundary have odd rendering behavior, notably with fog. Looking at them from certain directions, espeially when underwater, can make them appear as a solid color.
Java Edition Indev
0.3120100106The world boundary is now variable depending on the chosen world type. It may be even further customisable through world editing.
Blocks outside of the world can be targeted and even "broken", but will immediately revert to a prior state afterwards.
Block rendering has been reported to stop at a variety of different positions; X/Z: ±2,111, ±2,176 and ±2,304.[needs testing][more information needed]
Sky rendering stops at X/Z: ±2,560.[needs testing]
Minecraft Indev>20100203, <20100207-1After attempting to move a bit past the farthest distance that can be built, the player will be pushed back towards the center of the world with an increasingly hard force depending on their distance.
Java Edition Infdev
Minecraft Infdev20100227-1The world boundary has been completely removed, allowing the player to access terrain as far as the game itself is capable of handling.
A skybox (
 #0000FF) has been added. It stops at X/Z: ±1,024
20100313A new boundary has been set in place: blocks no longer generate beyond X/Z: ±32,000,000, giving way to the void.
Updating blocks next to this void causes an extreme amount of lighting updates, effectively freezing the game for an extended period of time.
The aforementioned skybox has been removed.
20100413Attempting to move past X/Z: ±32,000,000 will put the player in a permanent glitchy, jittery stasis[4] requiring external tools to escape.
Java Edition Alpha
v1.2.0?Beyond X/Z: ±32,000,000, phantom "fake chunks" (where chunks of bare unpopulated terrain render, but collision physics are completely absent) now appear. The blocks are not solid and can be fallen through.
Terrain beyond X/Z: ±32,000,000 would also not be populated with terrain features such as trees and blobs. As such, this allows the complete avoidance of a fatal distance effect involving ore generation between X/Z: ±67,108,864 and X/Z: ±134,217,728 which would otherwise cause runaway chunk loading and game crashes.
Unknown
?Many single blocks of water and lava generate at the edge of the world, which are actually springs, as the intangible blocks are considered air.
Java Edition Beta
1.8Pre-releaseThe "fake chunks" now start at X/Z: ±30,000,000, 2 million meters less than in Alpha v1.2.0 - Beta 1.7.3.
Using an NBT editor, beyond X/Z: ±30,000,032, the player gets stuck in a glitched position and need to use a program to make their character back. Beyond X/Z: ±30,000,064, blocks no longer render. The map is blank from here on out.[is this the correct version?]
Exceeding the 32 million block limit (only possible through nether portals or external editors) now causes the game to crash.[verify]
Java Edition
1.2.112w03aThe player's looking direction now freezes when going beyond the 30 million border, rather than the player's head twisting unnaturally on an unmoving body.
1.3.112w18aThe wall that freezes the character beyond X/Z: ±30,000,032 no longer exists, allowing the player to access terrain up to 32 million blocks.
12w27aNether portals are now limited to X/Z: ±29,999,872 in the Overworld.
1.7.213w36aMinecraft crashes after the player surpasses X/Z: ±29,999,840 on Default, Large Biomes, and AMPLIFIED worlds.
13w37aAll blocks at X/Z: ±30,000,000, including air itself, now act completely solid, creating an effective wall at this point.
This solid wall extends upwards to Y: 2,147,483,647,[more information needed] even though blocks cannot exist in these regions. As such, if a player is moved outside this boundary via commands or external tools, they are unable to move.
Walking on this wall far enough[more information needed] causes the game to crash.
Beyond the invisible wall, if items are thrown, the falling animation is jittery. The thrown item disappears upon contact with any block other than air.
Beyond X/Z: ±32,000,000, the player is kicked out with an "Illegal Position" message.
Some mobs (e.g. slimes) try to go past the world border, to no avail.
1.814w02aChunks beyond X/Z: ±30,000,000 now no longer render.
Blocks beyond X/Z: ±30,000,000 are no longer all solid, allowing players to move slightly beyond this point manually.
Actually moving beyond X/Z: ±30,000,000 will freeze the player in place, unable to move anywhere else without commands. Their hand and player model in third person view will disappear, and they will appear frozen in an animation in the survival inventory screen.
14w06aAttempting to move beyond X/Z: ±30,000,000 will now kick the player for being in an illegal position.
14w17aThe world border has been added. As it causes many effects unrelated to the actual edge of the world, see World border#History for further information regarding it.
Exceeding 30 million blocks now outright crashes the game rather than kicking the user back to the server list.
14w18aExceeding X/Z: ±30,000,000 now kicks the player again rather than crashing.
Some cases of the game completely freezing have been noted in versions with this behavior, forcing the player to close the window with Task Manager or the like.
The world border will always render and behave as though it is at ±29,999,984, even if set to be at a value beyond this. It can be set to be smaller however.
pre3There is now an effective "wall" at X/Z: ±29,999,999 preventing the player from surpassing it.
This wall is in fact the game simply teleporting the player to exactly X/Z: ±29,999,999 if their coordinates exceed X/Z: ±29,999,999, rather than a solid wall like was present in 1.7. As such, it results in some interesting visual quirks which were not present for the former, such as the player walking animation/view bobbing still playing while walking into it despite the player not actually changing their position.
Teleporting anywhere between X/Z: ±29,999,999 and X/Z: ±30,000,000 will cause the player to be immediately teleported back to X/Z: ±29,999,999 after one tick. Teleporting to exactly X/Z: ±30,000,000 will freeze the player in place (allowing them to teleport back), and teleporting anywhere beyond X/Z: ±30,000,000 will crash the game.
1.915w37aChunks beyond X/Z: ±30,000,000 are now rendered again, up to a variable limit, which as been reported as X/Z: ±30,000,224, ±30,000,240 and even ±30,000,496. Many of the issues surrounding block and item rendering have also disappeared; with this, the world boundary is now generally more stable. Also, the chunks beyond X/Z: ±30,000,000 are now solid and can perfectly generate structures like villages, mineshafts, and trees.
15w51aTeleporting past X/Z: ±30,000,000 is no longer possible; the player always gets teleported to X/Z: ±30,000,000, even when using external programs.
?Items no longer move erratically beyond X/Z: ±30,000,000.
1.1620w06aRain always appears at sea level beyond X/Z: ±30,000,000 (likely from fixing MC-131770).[3]
Pocket Edition Alpha
?Worlds are 256 blocks long in both directions. Whether the positions of the boundaries actually used to be consistent are unknown, although they are not in current Old worlds.
The edges of the world are made up of invisible bedrock. This extends up to 128 blocks and can be walked on forever.
v0.9.0build 1Added infinite world generation, which removes the boundary for worlds of that type.
?Nether portals can no longer be generated or place the player any farther than X/Z: ±31,999,872.
?/tp can no longer take the player past X/Z: ±30,000,000.

Java Edition pre-Classic
rd-131655The world has a bottom which can be fallen out of indefinitely. It is assumed to be at Y: ±0, as no proper way to view coordinates existed yet.
Java Edition Classic
0.0.12aThe bottom of the world remained unchanged despite the addition of bedrock to make it impossible to fall out of.
Java Edition
?Teleportation beyond Y: ±4,096 is no longer allowed.
?Teleportation beyond Y: ±4,096 is again possible.
?Teleportation beyond Y: ±20,000,000 is no longer allowed.
?Players are now kicked beyond Y: ±30,000,000.

Older version effects[edit]

Infdev[edit]

On February 27, 2010, version of Infdev, many side effects would occur as the player walked thousands or even millions of blocks away.

  • X/Z ±512–1,024: Clouds stop rendering.

In Infdev 20100327, walking off the edge would cause the player to become stuck in a glitched position, unable to escape.

In previous versions of the game, if the player teleported as high as they possibly could, they were sent to a Y-Axis of 3.4x1038. In this zone, the player floats without a purpose, and dropped items that slide with what appears to be no friction before suddenly stop after about 20 blocks. It has been reported that the X and Z-Axis sometimes flicker randomly in this zone. The memory pie chart also sometimes randomly jumps to 100% undefined memory usage, and then disappears upon re-entering the debug menu.

Fake chunks[edit]

As the player journeys even deeper into the Far Lands, the effects worsen to the point where the game is unplayable. At X/Z ±32,000,000, blocks are treated as permanently nonexistent, and do not generate even though they may appear to. When Minecraft generates and loads chunks, it loads an empty version of the terrain, complete with grass, stone and water textures that cannot be walked on. This map generates out to the 32-bit integer limit. The game can load chunks only out to X/Z: ±32,000,000, causing a problem between the noise map and the chunk generator. To fix this problem, Minecraft removes the chunks generated beyond X/Z: >±32,000,000 and generates only the noise map. If the player tries to walk on this map, they fall into the void. This value is hard-coded in the source code of Minecraft, meaning that it cannot be changed without editing the source files. Because chunks technically do not generate beyond X/Z: ±32,000,000, things like trees, falling gravel, falling sand, mobs, grass, and other entities do not generate either. This can make the map relatively stable and crashes can be somewhat rare; however, crashes can happen on low-end computers. In rare cases, if the player performs the "ghost spawn glitch" that worked in versions between Beta 1.6 Test Build 3 and Beta 1.7.3, the player can cause trees and plants to generate beyond ±32,000,000. However the framerate was actually much better the further one went because of no entities.

Console info[edit]

In the Xbox 360 Edition, PlayStation 3 Edition, PlayStation Vita Edition, and Wii U Edition, the Overworld is limited to 864×864 blocks. Additionally, in the Xbox One Edition, PlayStation 4 Edition and Nintendo Switch Edition, the player is able to further select the size of their worlds, from Small (1024×1024), Medium (3072×3072), and Large (5120×5120, except Nintendo Switch Edition). The edges of these worlds are surrounded by an invisible barrier with an endless sea of water beyond it.

Trivia[edit]

Please help improve this page. The talk page may contain suggestions.
  • Traveling from one edge of the world to the opposite edge by powered rail would take 35 days and 10 hours. Building the rails for such a trip would require enough iron and/or gold to fill over 723 double chests, even when packed into blocks, as well as sticks made from enough wood to fill over 135 double chests (as log blocks, not as planks, and excluding the redstone torches). (53 stacks of logs would be required just to make enough chests to hold all the building materials for this rail track.) If already crafted, the rails required would fill 17,361 double chests. If the player had to gather the materials to make all those rails, they would wear out 14,404 diamond pickaxes and 300 diamond axes (on average, about 3,601 diamond pickaxes and 75 diamond axes, both enchanted with Unbreaking 3).
    • Even if one were to amass all these materials, actually laying said track would require the player to travel the entire distance through other means anyway.
    • Factoring in the need for powering the track and assuming the player were to use redstone torches, the player would require 3,529,412 torches for the full track, since a torch can optimally light 17 blocks. That requires 55,148 sticks and bits of redstone dust, which requires 2042 large chests, which requires 128 stacks of log blocks to make the chests (which requires 3 large chests).
  • Traveling from 0,0 to the edge of the world by foot takes around 140 days.[6]
  • It is possible to generate trees and vegetation beyond 30,000,000 by loading a version of Minecraft after Java Edition 1.9, then load a few chunks beyond the world border. Then, close the world and load a version of Minecraft between Beta 1.8 - Release Java Edition 1.6-pre[verify] and load the same world. If the players travel to the world barrier, there are a few chunks that generate beyond 30,000,000 that have trees and grass.
    • It is possible to even generate Far Lands chunks using this method. Load a world in release Beta 1.8 - Release 1.6 and teleport to X/Z: 30,000,000. Close the world before the fake chunks generate and load the world in Beta 1.7.3. The Far Lands chunks load and then, the player can load as many chunks as they want. Then close the world and load it in a newer version, and the player has Far Lands chunks in the 30,000,000 block area.
  • Spiders can climb the border, continuing to climb upward indefinitely.[verify].
  • In Minecraft 4k, there is a barrier on the bottom of the map, which is unbreakable by any means.[7]
